RFID Power Tool Activation to Deter Retail Theft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current theft deterrent systems in retail environments, such as antitheft lanyards and locks, are costly, burdensome, and interfere with the checkout process, as they do not effectively prevent theft after the display lock is unlocked, leading to lost revenue and incorrect inventory reporting.
Innovation Solution
A system utilizing RFID-tagged power tools and battery packs that require activation through a tag programmer at checkout, where the tool or battery pack's functionality is restricted if not properly processed, ensuring it cannot be used until validated for purchase, using a controller and state circuit to manage power delivery based on activation state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional theft deterrent systems (antitheft lanyards and locks) are used, then theft prevention is improved, but device complexity and cost increase, and ease of operation deteriorates due to burdensome checkout processes
Solution Approach 1:
The patent extracts the theft prevention function from physical barriers (locks and lanyards) and relocates it to the power supply system. The RFID tag and controller within the battery pack or tool handle enable electronic authorization, separating the deterrent function from mechanical constraints and eliminating the need for complex physical deterrent systems at checkout.
Solution Approach 2:
The patent replaces mechanical theft deterrent systems (locks, lanyards, physical barriers) with an electronic authorization system based on RFID technology. The controller reads the RFID tag and electronically authorizes power delivery, substituting mechanical constraints with electronic control to simplify the system and improve ease of operation.
2Reliability
If traditional theft deterrent systems (antitheft lanyards and locks) are used, then theft prevention is improved, but ease of operation worsens due to burdensome checkout processes
Solution Approach 1:
The patent replaces mechanical theft deterrent systems (locks, lanyards, physical barriers) with an electronic authorization system based on RFID technology. The controller reads the RFID tag and electronically authorizes power delivery, substituting mechanical constraints with electronic control to simplify the system and improve ease of operation.
Solution Approach 2:
The system enables self-service checkout by allowing the RFID tag to be automatically read by the controller when the tool or battery pack is placed in the charging case or brought near the authorization point. The authorization process occurs automatically without requiring manual intervention or complex checkout procedures.
3Ease of operation
If RFID activation system is implemented, then ease of operation is improved with simplified checkout, but device complexity increases due to added electronic components
Solution Approach 1:
The patent merges the RFID tag, controller, and power management components into the existing battery pack or tool handle structure. This integration approach consolidates multiple functions (power storage, authorization, power delivery control) into unified components, minimizing the addition of separate electronic systems and reducing overall device complexity.
Solution Approach 2:
The controller serves multiple functions: it manages power delivery to the motor, reads and validates RFID tags for theft prevention, and controls the charging process. This multi-functionality reduces the need for separate dedicated components, thereby minimizing the increase in device complexity while maintaining simplified operation.

AI summary
A theft deterring system (100) includes a power tool (200, 250) with a motor (M) connectable to a power source, a switch (204) connected to the motor, a controller (203) controlling to the switch for controlling an amount of power provided to the motor, and a state circuit (206) having a memory (206M) for storing a state value. The controller (203) activates the switch (204) to provide power to the motor when the state value stored in the memory equals a desired value. The system may also include a tag programmer (150) for changing the stored value.
